No it isn't. http://www.arduino.cc/en/Serial/Begin I've run mine at 115200 and it works fine.

Re: Regarding The cRio
Isn't that still a seriously low level of bandwidth?

I guess knowing what you are passing back and forth, it might only have to come down to raw, simple data that gets proccessed, and the results are passed back just as simply, but still...

Re: Regarding The cRio
If you are seriously considering an arduino, then why don't you use one of the ethernet shields?

http://www.adafruit.com/index.php?main_page=product_info&cPath=17_21&produ cts_id=83
http://www.sparkfun.com/commerce/pro...oducts_id=9026

that would leave the serial port on the cRio open, and dwould allow a network switch to combine several on the robot.

The sparkfun shield communicates over SPI, which theoretically has a higher bandwidth then the serial comms that it is replacing

Don't other electronics, such as the Jaguars, use BIOS batteries?

No, only the compactRio has a bios battery for its real time clock.

I have a picture of the insides of a jaguar which i will edit my post to attach (can't find it right now)

There are cheaper alternate to the Arduino, the mbed, has CAN, Ethernet, file system and serial all built in at $50 only bad side id teh compiler is only online
